HANGER non TnoLLnY-wmEs.

Application filed March 21, 1912. Serial No. 685,232.

To all whom it may concern:

Beit known that we, WILLIAM C; STARKEY and G ENN H. Bonus, citizens ofthe United States, and residents of Mansfield, in the State of Ohio,have invented certain new and useful Improve ments in Hangers forTrolley-Wires, of which the following is a specification.-

Our invention "relates to suspension "devices for electric conductors,and has more particular reference to improvements in trolleywire'hangers, of the typegenerally known as catena'ry hangers. I I

The 0l316Ct, primarily of our invention, Is

to provide a cheap, efficient "and durable\ hanger for catenary systemsof suspending" trolley wires, Which will be exceedingl 7 strong, butlight in'weight. I

A further object is to provide an improved catenary hanger which can bemade of two parts, namely, a wire holding member and a suspensionmember,assembled in operative relation in a simple and efiicient Vmanner. l Afurther Ob ect isto'provide an improved trolley wire hanger which can bequickly and securely attachedfto the wire to besuspended, and which,when attached to the wire, will offer no obstruction whateverto thetraveling'trolleyor contact member.

To the attainmentofthese ends, and the accomplishment of other'objectshereinafter appearing, our invention consists in the fea- 1 tures'ofnovelty disclosed in the construction, j

combination and arrangement of parts shown in the accompanying drawings,which illustrate one embodiment of our invention, andin wh1ch- Figure 1is a view in elevation of our-im-- proved hanger attached to a trolleywire.

Fig. Qis an end'viewof the lower portion threofl-the Wire holdingmember'being shown in transverse section Fig. 3 is a transverses'ectional'view'on line 8-3 of Fig. 1;'-'

Fig; tis a side elevation 'ofthe wireholding member, the suspensionmember being" omitted; Fig. 5 is asimilar view OfaTnOdk fied form ofwire holdingfmember; Fig. ;6 is a view similar to'Figi 1 showing amod1-o tied structureembodying our invention; Fig;

7 is ,an end view thereof; 'and'Fig. 8 is a longitudinal, sectionalviewthereof on Inthedrawings we have shown our invn-j 131011 as embodiedin a hanger-which is adapted for supporting trolley'wires of thesecalled grooved and figu're 8 types, but it i s to be understoodthat ourimproved hanger is'equally as'well adaptedto the'round or other types ofwire.

The hangers or wire suspending devices, shown in the drawings eachembody a wire holdingmember A, and asuspensionmein' ber Bis disposedpreferably at substantially right angles thereto, and each memberthereof is composed preferably of a single piece of metal; The member orear A has a lower portion" 1 which agroove 2 is'formed for the'purposeof receiving the trolley wire-"3'.

Theshapeof this groove variesin accord ancewith the cross-sectionalshape of the Wire to be'hung. In fact, the groove or channel may begiven any desired shape,

butWe prefer that it conform to that ofthey wire so that a more accurateconnection may be made and then soldered therein if desired. The edgesor lips tarepreferab'ly made'bendable so that they can be hammered orpressed inwardly to embrace the wire,

when used with the grooved or figure 8 wire; the bendableQlips aremadeof such thick-- ness that when they are'forced or bent into thegroovesz5 of the wires as shown in- Fig. 8,1tlieylie within the generalconfines ofthe wireand donot noticeably-increase the size of the wire atthese points; For the sake of lightness in weight, without sacrifice tostrength, we make the portion 1 of substantially uniform thickness, andprovide thereon one or two integral members'or flanges 6 dependingon'theparticular requirements to which the hanger is tobe adapted. Theseupstanding members 6 constitute means to 1 which the suspension memberBmay be attached, and if desired they may be formed as a singleshort lugor lugs as the case may be: If the wireholding member A is made of'theso-called extruded brass which is, as

well known, "formed'by forcing brass in aheated} viscous state underhigh pressure through'a die (and'itis preferablyso made),

the flanges ,ormembers 6 extend the length off theylo'wer or wireholdingportion These members .or flanges" 6 also serve asstrengthening ribsagainst bending strains: 9 In Figs-.-1, 4t and 6 'weha've-showntheflanges as tapered toward the outer ends for the sake 1 for attachmentto the messenger wire. This permits the straps 8 to be cut from longlengths of stock strapmetal and a great saving in manufacturing expensesis accomplished. Figs. 1, 6, 7 and 8 show a method of forming the upperendsof the strap 8 for attachment to a messenger wire.

Asshown the upperportion thereof may be' doubled back upon itself toform a long loop 15, andthe end 14 may be turned laterally to close thelowerv end ofthe loop and prevent thehanger from becoming acci dentallyunhooked fromthe messenger.

As before intimated, the number of flanges 6 depends to some extent uponthe -manner in which the suspension member" B is to be attachedtothewire-holding mem her A. For instance, one flange or rib 6,

may be formed on the member and the lower end of the suspension strapmay-bedoubled back on itself or bent to form an eye, loop or hook 9.This may be hooked into a slot or spring 10 in the flange or rib 6(Figs. 1, 2, 4 and 5) and the .end portion 11 and the adjacent metal 12may be jammed together oroffset to close the hook and position thesuspension strap insubstantially central alinement with the member A. Itis seen, however, by referenceto F igs. 6, 7 and 8, that if desiredthemember A may be pro- 1 'vided with two parallel flanges 6 spaced apartto form a slot or channel into which the squared lower end 16 of thesuspension" strap maybe placed, and a rivet or bolt 17 passed throughsuitable holes in theflanges and strap to bind the parts together. 7

It is thus seen that our improved hanger possesses the combinedadvantages of sim} plicity, durability, cheapness in manufacture andneatness in appearance.
